    <p>In my application , user will input signature and the next time it will compare and do the authentication.</p> <p>I have see question on SO but I cant find how we compare. If we use gesture and store file as image , Its not correct as next time user might sign with little variation.</p> <p>I have tried comparing using Gestures it self but , firstly multistroke is not working properly and second predictions are not perfect.</p> <p>To add gesture to library : public void addGesture() { if (mGesture != null) { </p> <pre><code> final GestureLibrary store = getStore(); store.addGesture("ges", mGesture); store.save(); setResult(RESULT_OK); final String path = new File(Environment.getExternalStorageDirectory(), "gestures").getAbsolutePath(); Toast.makeText(this,"success", Toast.LENGTH_LONG).show(); } else { setResult(RESULT_CANCELED); } } </code></pre> <p>Comparing :</p> <pre><code>public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) { ArrayList&lt;Prediction&gt; predictions = mLibrary.recognize(gesture); Log.e("predictions","predictions----"+predictions.size()); // We want at least one prediction if (predictions.size() &gt; 0) { Prediction prediction = predictions.get(0); // We want at least some confidence in the result Log.e("SCORE","SCORE----"+prediction.score); if (prediction.score &gt; 1.0) { // Show the spell Toast.makeText(this, prediction.name, Toast.LENGTH_SHORT).show(); } } } </code></pre> <p>Can anyone suggest something regaurding this.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
